I'm looking for recommendations for a photo-viewing app for my iPad; Apple's "Photos" app has too many bugs and limitations for my needs. What I want seems simple -- an elegant way with which to impose my photos onto someone hapless to come within an eyeball's reach of me -- but I haven't found it yet.

Features that I hope for:

Clean, simple, uncluttered interface.

Photo update via FTP, Dropbox, or some other method where management is done on my computer and merely reflected to the device.

Supports display of basic metadata on each photo, when asked.

Supports display of [...]

This post is of interest only to Lightroom plugin developers.

Round about Lightroom 3.2, Adobe added support for intercepting "lightroom://" URLs, but have not documented it yet, so I'll do so here. It's particularly useful as part of an OAuth-authentication procedure.

What

You can have your plugin automatically respond to certain "lightroom://" URLs if they are formatted correctly, and if you add appropriate support to your plugin.

The "your.plugin.id" is the LrToolkitIdentifier [...]

In the comments of a recent post about GPS receivers, it was suggested that the GPS receiver in the iPhone was useful for keeping tracklogs. I had bad experiences with iPhone location services when I tested in 2009, but perhaps my test wasn't good, or perhaps the old iPhone 3 wasn't good, so I thought I'd give it another try.

So, the other day I took three GPS receivers with me while I did some errands. As I'm apt to do lately, I walked.

This post is a comparison of the resulting tracklogs.

The three devices I took along on [...]

Now that Nikon has announced its next flagship pro SLR, the Nikon D4, with much flowery prose but few hard details, discussion and debate and speculation and flames and praise have filled camera circles.

This post is long, but here's the two-sentence summary for the "tl;dr" crowd:

As with most any technology release (hardware or software), folks tend to frame their personal whims and desires as "absolutely required!", while features that they don't personally care about become unneeded fluff. Photographers who don't care about video, for example, lament the assumed cost of all the new video features.

Rarely does a photo take my breath away, but this rendition by Paul Barr does it every time I come across it. I don't know what it is about it, but if you'll excuse the pun, I'm really drawn to it.

Paul recently got an iPhone 4s, and to complement its camera he loaded a few photo-processing apps, and spent some time over coffee futzing with the apps to get a feel for them. He ended up with a jumbled mix of results, almost all of which are interesting (though one really creeps me out), but the one above really [...]
